They would further shape the flake beating it with a bone or stone until it took on a more finished shape. They would then use a pointed bone or stone to chip flakes of the edge of the arrowhead to created a serrated edge. So there were different tools, a bone or stone hammer, a bone or stone 'flaker' to make the edge. Fire was used as a tool and some used leather pads as gloves. Some indians even used very basic hand or bow powered drills to help fashion items. I'm sure there were many other tools and methods. Hope that helps. -tony
